(2) Next, as shown in Fig. 26, when the replacement key CK is inserted into the keyhole 3 00, the replacement key CK is rotated by only a degree (45 degrees) in the clockwise direction, by replacing the key CK toward The insertion operation of the keyhole 3 00, and the auxiliary pin 700 which moves to the upper pin hole Ε1 side after the function of the key tooth of the replacement key CK exceeds the tangential line SL, and remains directly in the upper pin hole Ε1, when the storage bag ΡΕ When the upper pin holes 1 are aligned, the auxiliary pin 700 is stored in the storage bag holster according to the elastic force of the spring that pushes the upper pin 3 toward the protruding direction. (The -10-200902818 two-dotted line state in Figure 26). Further, the auxiliary pin 700 which does not exceed the tangent line S L and is located in the pin hole F2 below the inner cylinder 400 is rotated together with the inner cylinder 400. In the case shown in Fig. 27(A), the storage bag cover and the upper pin hole are in a state of being aligned, and the auxiliary pin 7 00 ' that moves beyond the tangential line SL toward the upper pin hole side is stored in the storage bag cover. FIG. 27(B) is a partial cross-sectional view showing an important part in a state in which the auxiliary pin 700 has been stored in the storage pocket, and FIG. 27(C) is a reset by a control member. After the member, a partial cross-sectional view of an important portion of the state in which the auxiliary pin is lifted up.

As shown in Fig. 27(A) and (B), when the auxiliary pin 700 is pressed against the pin holes El, N1, Q1 side by the key teeth of the replacement key CK, and the inner cylinder 400 is rotated by α degrees, the auxiliary pin 700 will be stored in the storage bag cover PE, ΡΝ, PQ, respectively. In this way, the replacement key CK is inserted into the keyhole 3 00 and rotated by a degree in the clockwise direction, and the auxiliary pin 700 on the side of the upper pin hole is accommodated by the action of the key tooth of the replacement key CK. In this state, the storage bag cover 'is rotated by a degree of rotation in the counterclockwise direction and then pulled out, and the replacement key CK is set as a backup key that can be opened/closed. In the above-described setting state, in the twenty-fifth diagram of the Ζ2-Ζ2 section of Fig. 20, three auxiliary pins 700 located at three positions of the columns ε, Ν, and Q are removed, and all unused weights are formed. The key tooth pressure of the replacement key CK set in the state setting state remains in the state of the pipe string on the pin hole side auxiliary pin 700. -11 - 200902818 (3) Next, according to FIG. 27(B), it is explained that the state in which the replacement key CK is set as the backup key is restored to the reset state in which the other replacement key CK can be set as the backup key. effect. Although in the above description, it is mentioned that the reset member 900 is between the respective roots PB2, PC2, PE2, PF2, PH2, PI2, PK2, PL2, PN2, P02, PQ2, PR2, PT2, PU2, PW2, PX2. Formed with a top, but between the roots PB2, PC2, PE2, PF2, PH2, PI2, PK2, PL2, PN2, P02, PQ2, PR2, PT2, PIJ2, PW2, PX2 and the top, respectively, a gentle slope is formed unit. Therefore, in the set state of Fig. 27(B), as shown in Fig. 27(C), the pin front end of the control member 910 having the press-out pin 911 having a section smaller than the reset pin insertion hole 900B is inserted from the pin. The hole 900B is inserted, and the auxiliary member 900 is pushed away against the elasticity of the spring 900A by the tip end of the pin, and is accommodated in the storage pockets PE, PN, and PQ along the inclined portion formed in the reset member 900. The pin 700 is moved by the aforementioned tilting portion of the reset member 900 against the respective pin by the movement of the control member 910 toward the idling direction of the reset member 900 (the left direction in FIG. 27(C)). The spring pushes the upper pins E3, N3, and Q3 upward. Next, in the state in which the reset member 900 shown in Fig. 27(C) is completely immersed, each of the auxiliary pins 700 is countered by the top formed between the root portions PB1, ..., PX1 of the reset member 900. The upper pins E3, N3, and Q3 are pushed up by the spring force of the spring, and the auxiliary pins 700 are moved from the storage pockets PE, PN, and PQ to the upper pin holes E1, N1', Q1. When the above state ’ is maintained and the control member 91 is rotated counterclockwise -12-200902818 by a degree, the control member 9 1 0 is pulled out, and the setting of the reset state is completed. In other words, each of the auxiliary pins 700 positioned in the storage pockets PE, PN, and PQ returns to the original state shown in Fig. 22. [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. 2005-341287 (Unpublished). [Problems to be Solved by the Invention] As described above, the cylindrical locks of Patent Document 1 and Patent Document 2 are cylindrical locks for taking out the auxiliary pin of the replaceable key to the outside, and Patent Document 3 provides a method of accommodating the auxiliary pin. The storage pocket of the inner cylinder 400 provided inside the cylinder lock 1 can be changed to a cylinder lock of another replacement key CK by performing a reset operation from an external reset key, and the main lock cannot be set. The problem with the keystrokes. In the article disclosed in Patent Document 3, in the case where the cylindrical lock 100 in which the master key can be set is formed, even all of the cylinder locks 1 0 0 shown in Fig. 22 (Fig. 20, Ζ2-Ζ2 sectional view) 0 auxiliary pin 7000, the upper pin A3 Χ3 is lifted by the key tooth against the spring, and is set to be placed on the key pin located in the upper pin hole A 1~X 1 to form any other alternative The state of the key CK can be used to unlock the key using the master key. However, if the cylinder lock 100 is inserted into the keyhole 300 and rotated by a degree in the clockwise direction, all the auxiliary pins will automatically fall into the storage pocket to form a storage, and the automatic setting is automatically impossible. Other -13 - 200902818 replacement key to open / close the lock state (off state). Therefore, it has the following problem: Once the master key has been used once, the function of the original master key is reached, which means that the replacement key CK cannot be used to open/close the lock. In order to achieve the function of the master key, once a plurality of cylinder locks have set any of the replacement keys CK as a backup key, the master key can be used to open/close the lock, and the replacement key CK set in advance as a sub-key must be used as Backup key is used. However, in the cylindrical lock of the above-mentioned prior invention, there is a problem that once the master key is used, the replacement key c K previously set as the sub-key cannot be used as the backup key. It is an object of the present invention to provide a new cylindrical lock that solves the above-mentioned conventional problems. [Means for Solving the Problem] The present invention provides a cylinder lock which is a plurality of upper pins disposed in a long axis direction of a cylinder outside the cylinder lock; and all of the lower pins corresponding to the inner cylinder of the upper pin, respectively Or any one of the auxiliary pins is interposed, and the cylinder lock can form a state of resetting, the reset state can open/close the lock by using a plurality of keys suitable for the keyhole of the cylinder lock; and setting a state in which all or any one of the plurality of auxiliary pins sandwiched between the upper pin and the lower pin is removed from the upper pin and the lower pin by external operation from the reset state, and The auxiliary pin is held in a housing state formed in the housing hole formed in the inner tube, and the lock can be opened/closed by using a specific key among a plurality of types of keys. The cylinder lock of claim 1 is characterized in that it has at least: an outer cylinder, the outer-14-200902818 cylinder has a plurality of upper pin holes in a long axis direction; and the inner cylinder is rotatably inserted in the outer cylinder, and has a plurality of lower pin holes corresponding to the plurality of upper pin holes of the outer cylinder, and after being pushed to the inner cylinder by the spring, the spring pin is pushed into the inner pin and the lower pin of the pin hole under the inner cylinder The cylindrical lock of the key for removing/closing the auxiliary pin from the upper pin and the lower pin is formed at any position, and a heave hole is formed in a longitudinal direction of the outer circumferential surface of the inner cylinder, and is formed in the foregoing a plurality of grooves that communicate with the receiving holes. When the oblong-shaped receiving holes are formed at a position behind the rotating inner tube, the length of the receiving holes in the longitudinal direction is used to isolate the upper pin holes and the adjacent upper pin holes. The set-reset member is slidably disposed in the fixed-reset member: the top portion and the root portion are interconnected end faces, and the front side and the top portion of the tilt portion are disposed between the rear side and the top portion of the root portion There are stage parts between them, and the following states are formed: State: the setting state is that when the key suitable for the front hole is inserted, the auxiliary pin is accommodated in the upper pin hole by the action of the key tooth of the key, and is formed by rotating the inner cylinder a state of being placed at the top of the setting-resetting member of the upper pin hole, and the same setting-resetting member is made according to the state, so that the top portion can be self-piercing and the pair is inserted into the aforementioned The upper pin; and the auxiliary pin are inserted, and the plurality of oblong shapes can be changed. The upper pin hole is formed by the groove formed between the wall and the partition wall, and the grounding is formed at the inclined portion thereof, and In the state in which the pin of the inner cylinder is pinned and the pin hole of the lower pin, the auxiliary pin abuts on the position of the -15-200902818 that is abutted from the external auxiliary pin to the position opposite to the root. When the reset member is pushed in the longitudinal direction of the groove, the auxiliary pin is accommodated in the housing hole of the inner cylinder by the spring force of the spring of the upper pin, and the spring of the setting-resetting member is removed once the pushing is released. Bomb thrust 'from the aforementioned - the step portion of the reset member pushes the auxiliary pin accommodated in the housing hole, and moves to the position facing the partition wall along the longitudinal direction of the oblong-shaped receiving hole of the inner tube, and the partition wall and the receiving hole And a set-reset member phase portion for maintaining the auxiliary pin removed from between the upper pin and the lower pin; and a reset state, the reset state is a key inserted in a key hole suitable for the inner cylinder, and the inner cylinder is rotated After the receiving hole and the upper pin hole are opposed to each other, the auxiliary pin is connected to the auxiliary pin by pushing the driving amount larger than the pushing amount of the setting-resetting member in the set state to the length of the groove. The action of the inclined portion of the root portion is pushed from the state of the root portion of the oblong receiving hole toward the pin hole side, and the auxiliary pin that is pushed into the upper pin hole is held in the upper pin hole by the top portion connected to the inclined portion, and the pin is held. Setting-resetting the pushing state of the member and simultaneously rotating the inner cylinder until the position of the upper pin hole and the lower pin hole is opposite, and temporarily releasing the pushing state of the setting-resetting member Auxiliary pin hole in the housing between the original back on the pin and the lower pin. (Action) According to the present invention as described above, in the normal state, for example, once the inner cylinder is rotated by operating the key as a backup key, the top of the aforementioned setting-resetting member will form a confrontation (facing) The pin hole is driven by the external operation of -16-200902818 to push the set-reset member so that the top portion forming the confrontation becomes the root portion. The auxiliary pin received in the upper pin hole will be pushed by the spring of the spring inserted into the pin hole. The auxiliary pin is housed in the housing hole of the inner cylinder. Further, once the setting-reset member is released, the spring force of the spring of the setting-resetting member is used, and the partition wall, the receiving hole, and the setting-reset member are formed in the stage between the upper pin holes. The auxiliary pin that is removed from between the upper pin and the lower pin is moved in the long-axis housing hole in the long-axis direction to form a hold (set state). In the set state, all or one of the auxiliary pins sandwiched between the upper pin and the lower pin is received in the housing hole, and only a specific key including the key as the backup key can be accepted. /Off lock. Further, in the case where all the auxiliary pins are housed in the housing hole, when the key is inserted into the keyhole, only the main key forming the following state can be accepted to open/close the lock, and the master key is formed: The boundary surface between the upper pin and the lower pin in the state in which the auxiliary pin is not interposed is identical to the tangent line, and the boundary surface between the lower pin and the auxiliary pin is aligned with the tangent line when the pin is inserted between the pin and the lower pin of the auxiliary pin. Further, even when a key other than the master key is set as the backup key, when the main key is inserted into the key hole, 'just push all the auxiliary pins sandwiched between the upper pin and the lower pin toward the upper pin hole side' or Forming a key tooth that can match the lower pin and the auxiliary pin, or between the lower pin and the upper pin and the tangent line. Even if the cylinder lock is formed by a specific key, the main key can be used to open/close the lock, even if The main key to open/close the lock and rotate the inner cylinder 'can be blocked by the top of the setting-resetting member as long as the setting operation of the resetting member with the external operation is not performed: by the aforementioned master key -17 - 200902818 The key is inserted into the keyhole, and the auxiliary pin temporarily stored in the pin hole on the outer cylinder is housed in the housing hole of the inner cylinder. Therefore, even if a temporary on/off lock is executed in the case where the main key is used to open/close the lock, the previously set specific key can be used as a backup key and can be executed as long as the external operation setting operation is not performed. On/off lock. Further, the key or the main key as the backup key is inserted into the keyhole and rotated, and the auxiliary pin housed in the storage hole state faces the upper pin hole, and the set-reset member is set to the set state by external operation. When the operation is further pushed forward, the inclined portion of the setting-resetting member acts to oppose the spring force of the spring of the pin hole, and moves the auxiliary pin to push from the receiving hole toward the upper pin hole. Then, 'turning the key while maintaining the state, and by releasing the external operation of the setting-reset member', the set-reset member can be retracted to the rear of the state before the external operation is performed, and can be temporarily removed. The auxiliary pin returns to between the upper pin and the lower pin (reset state). In this case, even if the main key other than the specific key set as the backup key can be reset, the present invention can be temporarily used even if the specific key previously set as the backup key is lost. The key performs a reset state and can even set other keys as backup keys. In the above-described setting-resetting member, in the embodiment to be described later, a spring that can be constantly pushed toward the rear side is provided, and in the case of pushing forward toward the front by an external operation, it is configured to oppose the spring thrust of the spring. The push is formed, and the set-reset member is automatically moved to the rear by the spring force of the spring once the external operation is released. However, the present invention is not limited to this. -18- 200902818 As long as it is a set-reset member The configuration can be movably operated, and once the external operation is released, the receiving hole can be faced and the root portion of the setting-resetting member can be made uniform. In the case of constituting the above structure, the setting-resetting member is often used in addition to the spring. In addition to the method of elastically pushing the rear side, the above-described spring may be configured in such a manner that at least the front end side of the set-reset member is formed by the magnetic body, and the set-reset member can be constantly pushed backward. And on the side wall of the front end side of the groove of the inner cylinder into which the reset member is inserted, the same magnetic body as the set-reset member is provided, and the same pole is used. The repulsive force of the magnetic body periodically pushes the set-reset member to the rear direction. The system using the cylinder lock of claim 2 of the present invention is constituted by the cylinder lock of claim 1, wherein the cylinder lock of the claim 1 is on the front side of the key hole forming the inner cylinder, and a setting-reset is inserted therethrough. a pin insertion hole for connecting the outer portion and the groove, wherein the groove is in communication with the plurality of receiving holes; and the first jig, the first jig is for performing an external operation, The external operation is performed by inserting the first pin of the first jig having the first length into the set-reset pin insertion hole and pressing the first pin into the first length, thereby setting the top of the set-reset member. The state in which the pin hole is opposed to the state of the pin hole is the state in which the first pin of the first jig is fixed to the key for performing the setting operation after being inserted into the key hole, and the key is used. a length inserted into the keyhole; and a second jig by inserting a second pin of the second jig having the second length into the set-reset pin insertion hole and pressing the second pin The distance of the second length causes the aforementioned auxiliary pin to be located long Shape storage -19- 200902818 The state of the root of the hole is pushed to the upper pin hole side by the action of the inclined portion connected to the root portion, and the second length means that the second pin of the second jig is fixed to the insertion key hole. The length into which the key is inserted when the key is inserted into the keyhole, and the second length is longer than the first length. [Effect of the Invention] According to the present invention, it is not necessary to take out the auxiliary pin from the upper pin and the lower pin to the outside, and it can be accommodated in the housing hole of the inner tube, and the auxiliary pin accommodated in the housing hole can be returned again. In the case between the upper pin and the lower pin, 'there can also be returned between the upper pin and the lower pin by the aforementioned external operation. Therefore, it is possible to form a plurality of key changes not only by combining the auxiliary pin clamps with any position between the upper pin and the lower pin, but also by moving between the upper pin and the lower pin to the aforementioned storage. The auxiliary pin of the hole returns to the position between the original upper pin and the lower pin, so that the key that becomes temporarily unusable can be reused again and again in an unlimited number of times. Further, since the housing hole for temporarily storing the removed auxiliary pin is elongated, the length of the auxiliary pin along the oblong receiving hole can be made by the press-fitting operation of the setting-resetting member in two stages. The direction moves, and the position can be changed, and is called the opposite operation of the setting operation and the reset operation.
